First of all, consider putting her to bed much earlier. I'd say between 6-7! I know it seems crazy, but my son starting sleeping 11-12 hours a night once I did that. He was around 4 months, and rarely woke up for a feeding! That early bedtime keeps babies from getting overly tired, and lets them get a really solid night of sleep.
Also, make sure your daycare is getting her to nap as well as possible. Soon, she'll be ready for a nap schedule. And she probably will need 2-3 good naps a day. This will also help her night sleep!
Finally, be ready for crazy sleep ahead no matter what you do. Soon she'll be rolling over, sitting up, getting teeth, crawling, etc. All that stuff, in addition to the nasty colds she's going to get for a while from daycare, will have an enormous impact on her sleep. If you stay consistent, she will find her way back to her good patterns. But it's not easy for baby or mama! :)
At some point, you may want to teach her to soothe herself to sleep. But not until you think she's ready. She may be too small/young right now. Every baby is different on that score. Also, you may want to eventually stop swaddling her, too. She's getting bigger and stronger, and it will become an issue when she wants to roll over!
Good luck! She'll figure it out!
